Passage Summary: Researchers say we don't use our hands as much when talking about 'big ideas' compared to 'physical things.' Critics point to people who do gesture during big ideas, but the author says those people might just be imagining those ideas as physical movements.

Conclusion: The existence of apparent exceptions is not a sufficient reason to dismiss the claim that people gesture less when discussing abstract concepts.

Reasoning: Some people may perceive words that are technically abstract as representing physical actions, meaning their gestures actually align with the researchers' theory rather than contradicting it.

Analysis: The author is defending a hypothesis by reinterpreting the evidence used against it. It’s a clever move: instead of denying that the gestures happen, the author suggests the critics have miscategorized the speaker's mental state. You should identify this as a defense of a correlation by providing an alternative explanation for the supposed counterexamples. It's like saying a 'no-sugar' diet isn't failing just because someone is eating fruit; they just don't count fruit as 'sugar' in the way the critic does.
